The design is almost complete so thought I would share it.
The remaining part is the connection between booms and the chassis, which needs to be strong and provide vibration resistance.
All I've come up with so far is a 'rubber grommet sandwich' with M4 bolts/washers etc, seems simple but somehow inadequate.
The PixFalcon will have its own foam/gel damper but extra isolation seems worth the effort.
Ideas & inspiration welcome :-)
